Application filed October 9, 1915. Serial No. 54,928.

To all whom it may concern:

'Be'it known that I, BRUCE 0. WHITE, a

a citizen of the United States, residing at New York, county of NewYork, and State of New York, have invented certain new and usefulImprovements in Cleaning Devices for Printing-Machine Inking Mechanism,

"fully described and represented in the following specification and theaccompanying drawings, forming apart of the same.

This invention relates to certain improvements in inking mechanism forprinting machines, andparticularly to that type of inking mechanism inwhich the ink is dis tribut'ed by means of a plurality of nozzles, anozzle being provided for each column or section ofth-e form, the inkbeing delivered to these nozzles under pressure, which may be producedby a series of pumps. In

this type of inking mechanism the ink is delivered by the nozzlesthrough small orifices and it sometimes occurs that these or1- ficesbecome choked or stopped up by ink,

up while the machine is operating. Be-

to produce a construction of simple form,

cause of this liability to stoppages, especially when the, mechanism isrunning, it is necessary for the attendant to examine the deliveryorifices from time to time to see if the ink is being properlydelivered,

or papers will be spoiled. When a stoppage occurs it is necessary toclean the orifice with a piece of wire or other tool. If several of theorifices become stopped up,

this method of cleaning requires time to perform, and this method ofcleaningorifices is for this and other reasons unsatisfactory.

It is the object of the present invention by which in a machineemploying. a plurality of ink delivery nozzles or orifices all thenozzles or orifices may be simultaneously cleared from time to time bythe attendant,

' and construction of such characters that when the mechanism isnotbeing operated, the device may be used to close up the nozzles and thuskeep the ink from drying in them and stopping them up.

For a full understanding of the invention a description will be given ofthe preferred form of an apparatus embodying the same in connection withthe accompanying drawings, in which Figure 1 is a side elevation, partlyin section, of so much of an inking mechanism of the type referred to asis necessary for a full understanding of the invention, and

Fig. 2 is an end View, partlybroken away, of the mechanism shown in Fig.1, lookin toward the left in that figure, the distributing cylinderbeing omitted.

The inking mechanism with which the mechanism shown is especiallydesigned for use is fully shown and described in my prior applicationSerial No. 38,528, and only so much as is necessary for a fullunderstanding of the present invention is here shown, and this will beonly briefly described.

Referring to the drawings, there are pro vided a plurality of supplyconduits or pipes 1 to which ink is delivered under pressure from areservoir provided with a plurality of pumps, one for each ink conduit,these pumps, the reservoir and con-.

nections to the conduits not being shown. These ink conduits or supplypipes have their delivery ends arranged in line along a.

passages 6 before described, this bar also acting to divide thesepass'ages from each other to column or other form section width.

The inclined surface 8 extends substantially into contact withjthedistributing cylinder 2 and theink from the orifices 7 spreads inflowingdown the incline so as to form a 'contlnuous thin stream or layer ofink-in contact with the distributingcylinder. These small orifices 7,-as before stated, are liable to become stopped up or plugged up withink, and in accordance'with the present invention means are providedwhereby thesenozzles can be'- simultaneously cleared all alongthecylinder from time to time the attendant, so that the necessity forexamining them is done away with and a free and clear distribution ofink from all the nozzles is assured, and, in' the event of several ofthe nozzles becoming stopped up or plugged, they can all be cleared atonce, and the time consumed iirseparately cleaning them is saved.VVhile' the particular construction for effecting this may be varied, inthe preferredembodiment of the 1 invention there will be provided aplurality ofjcleaner or ejector pins 10, one pin being providedfor eachorifice. 'These ejector pins are mounted in alinement with the orificesand operate seas ton-simultaneously move into the orifices; the pinsbeing dimensioned to snugly fit the orifices and effectually'remove fromthem any foreign material which may cause stoppage.

A convenient construction which may, however, bevar'ied in its details,for effecting the simultaneous movement 1 of the ejector'p'ins is'thatshown in the drawings. As illustrated the-pins are carried on a bar 11extending-across the distributing-mechanism, the pinspassing throughholes in the nozzle piece or bar 9 before referred to. These holesin bar9 are in alinement with the orifices and are of suflicient depth to actasaguide' for the pins when they are moved u, soTas to "insure theirproper movement into the orifices, the nozzle piece 9 being providedwith a depending portion 12 in which these" holes are formed. In theparticularconstr uction" illustrated, the orifices 7 are arrangedvertically and the pin-carrying 'barlll is'given a lifting movement tomove th'e'pins in and out of the orifices. As

shown, this movement is effected by mounting the bar 11 in a pair ofbrackets 13, 11, secured to the casing 3, the bar being verticallymovable in its brackets. Also mounted in these brackets and extendingacross the machine is a shaft 15 which has collars 16, 17 fast thereon,these collars being provided with extensions or lugs 18 taking intoslots in the bar 11. The shaft is rotated and the bar 11 lifted by meansof a suitable handle 19. If desired, springs 20, taking between thebrackets and the collars may be employed for cushioning the upwardmovement of the ejector pins and assisting to some extent in the returnthereof.

With this construction, allthe nozzles can be cleared of inksimultaneously by the attendant bysimply' manipiilating the handle, andthis can be'done so frequently as to obviate the necessity forexamining-the nozzles. This construction is ail-especially convenient'onefor the upper decks of ma chines where there are two or more decksof inking mechanism, in that the ejector bar operating handle I may belocated on the floor and the ejector bars of each deck connected byrods, so that all can be operated simultaneously. Furthermore, thenozzles can be completely sealed by the ejector'pins whenthe machine isnot being operated.

While the invention has been shown in connection with a plurality ofnozzles having small ink delivery. openings, it will be understood thatthe invention is capable of use with other forms of nozzles and is nottobe restricted to the particular form shown and described.
